Abstract

With a face plate 3 of a lathe for clamping the ends 44 of workpieces, having several guides 11, 12, 13 14 which are let in offset in the radial direction and to which in each case a displaceable clamping claw 15, 16, 17, 18 and a drivable clamping spindle 19, 20, 21, 22 are allocated, each individual displaceable clamping claw 15 to 18 forming a screw drive 23, 24, 25, 26 with the associated clamping spindle 19 to 22, and a reduction drive being arranged in each clamping spindle 19 to 22, rapid alignment of a clamped end 44 of a workpiece with the axis 46 of rotation of the face plate 3 without stopping the face plate is achieved by the face plate 3 carrying a concentrically mounted gear rim 27 which can be driven by a geared motor 29 and drives each reduction drive, designed as a planetary drive 41, 42, of each clamping spindle 19 to 22 in each case via a gear 35, a first shaft 37, a clutch 39, a second shaft 38 and a bevel-gear drive 40. <IMAGE>
